Ingredients Notes

The key to a perfect Peanut Butter sheet cake is using quality ingredients. For the best results, choose creamy peanut butter. Feel free to use a natural or organic brand, but ensure it’s the no-stir type. You can substitute brown sugar with coconut sugar for a healthier twist, and whole milk can be swapped with almond milk for a dairy-free version.

Recipe Steps

Step 1

Preheat your oven to 350°F (175°C). Grease a 9×13-inch Sheet Pan with butter or non-stick spray. Set aside.

Step 2

In a large bowl, combine all-purpose flour, baking soda, baking powder, and salt. Sift together to ensure there are no clumps.

Step 3

In another bowl, cream together the Peanut Butter and sugars until light and fluffy. Add eggs one at a time, mixing well after each addition.

Step 4

Slowly alternate adding the dry ingredients and milk to the peanut butter mixture, starting and ending with the dry. Mix just until combined.

Step 5

Pour the batter into the prepared pan. Smooth the top with a spatula and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let it cool before frosting or serving.

Storage Options

Wrap the cake tightly in plastic wrap or place it in an airtight container. It will stay fresh at room temperature for up to four days. To freeze, slice the cake and store the pieces in a freezer-safe bag for up to three months. Defrost at room temperature or warm slices in the microwave for a fresh-from-the-oven experience.

Variations & Substitutions

For a gluten-free version, substitute the flour with a 1:1 gluten-free baking blend. Add chocolate chips to the batter for a chocolaty twist. You can also use almond butter or sunflower seed butter for a different nutty flavor.

Serving Suggestions

Serve the peanut butter sheet cake as a delightful dessert at birthday parties or picnics. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for an extra treat. For a festive touch, sprinkle the top with crushed peanuts or chocolate shavings before serving.
